Responsive Design Exercise

Some time ago, I did a exercise for apply a job. This was the exam I made. I think is a good idea for practice your front-end skills. So, if you have some time and want a challenge for Sunday morning, you can try on your own to complete the task.

The exercise seem to be very simple (it doesn’t): create the markup of
this design for mobiles, tablets and desktop. Check out my version. Maybe I’ll improve it soon. I don’t know if the approach was the
correct, but it works in three different devices!.
